metathorax very distinct, with a median groove, and strong, regular, oblique stride ; 

 sides of metathorax striate-punctate ; tegulse dark reddish, with a large yellow spot 

 in front ; wings clouded on costa and apex as usual, the nervures ferruginous ; 

 second submarginal cell petiolate above ; second recurrent nervure practically meet- 

 ing second transverso-cubital ; coxae black with a yellow spot in front ; femora yellow 

 with a large black area, pointed apical, behind, this on the hind femora nearly en- 

 closing a yellow mark; tibire yellow with ferruginous spines; tarsi with the basal 

 joint more or less yellow, the others ferruginous ; abdomen yellow marked with 

 black, the yellow parts very sparsely punctured, except towards the bases of the seg- 

 ments, the black parts roughened ; first segment black with a broad yellow band, 

 deeply notched anteriorly and posteriorly in the middle ; second broadly black at base 

 and with a transverse median black mark ; third to fifth narrowly black at base, the 

 third and fourth with a long transverse black mark ; sixth black, except the hollowed 

 areas on each side of the pygidial plate, which are yellow; pygidial plate narrow; 

 venter yellow, banded with black. 



One specimen : White Oaks, New Mexico, collected by Miss 

 Bertha Chapman. 



Eucerceris chapmange, new species. 



J' . Length 13^-2 nun., black and yellow. Similar to E. striai entiis, but differing 

 as follows (part of the difference being sexual): Eyes much larger, face much nar- 

 rower ; clypeus without any black denticles on margin ; scape shorter and thicker and 

 yellow in front ; flagellum black, the second to fourth joints reddened beneath ; cheeks 

 with no yellow band, but only a small spot on upper part; metathorax quite closely 

 punctured all over; scutellum entirely black, yellow marks on metathorax much 

 smaller ; second submarginal cell joining marginal ; second recurrent nervure joining 

 third submarginal cell about as far from its base as first recurrent nervure is from base 

 of second submarginal ; black area on hind femora not enclosing a yellow mark ; hind 

 tibiae with a black apical patch on inner side ; abdomen black with six bright yellow 

 bands, that on second segment with an anterior process on each side directed antero- 

 mesad ; claspers very large, the apical half strongly hairy above ; ventral surface of 

 abdomen yellow, as also is the under surface of the thorax. (In E. striareatits the 

 sternites are entirely black). 



One specimen, collected by Miss Bertha Chapman, after whom it 

 is named. It is believed to be from White Oaks, New Mexico, but 

 there is just a possibility that it came from the Yosemite, California. 

 This insect looks like the male of E. striareatus, but the sculpture of 

 the mesothorax, the pattern of the abdomen and color of the sternal 

 parts are entirely different. The top of the head and the anterior 

 part of the thorax are quite hairy, the hair being of a sordid whitish. 



Eucerceris montana Cresson. 



Twenty-two specimens; twenty from Highrolls, Sacramento Mts., 

 N. M., May 29 to June 3, 1902 (Viereck) ; two from Amogordo, 

 N. M., May 13, 1902 (Viereck). Also found in the Mesilla Valley.
